/*
How localization works ?
=> See Z-curve identification
We use Z-curve to ID the quadtree nodes and we flip the bit of the level.
For example if we are in the third level of quadtreefication and we have the ID 2:
0000 0000 0001 0010
^ ^
| ID of the node
Bit flipped for the level
With this technique we can store a 32 bits localization to allow 15 levels of details
and know the parents of any node due to the Z-curve :D
